I applied to the job and also got an employee referral. It was a little over a week before I got the initial call asking to schedule a phone interview. The phone interview was scheduled for 4-5 days later. The phone interview went alright, but could have gone better on my part. I had actually spent a lot of time researching the company, looking up interview tips and questions on this site and others, and asked my contact at the company what the process had been like for her. But when I was asked what I did to prepare I spaced on all that and didn't go into enough detail - I think they wanted to know how serious I was, but the question was so simple that I hadn't really expected it and was sort of caught off guard. I felt that I didn't answer it very well and didn't really regain my footing. So be prepared for the simple questions! I should have gone over more typical interview questions.
The interview lasted about half an hour, at the end of which the interviewer said that I seemed to have great customer service skills but could work on my technical skills, like HTML/CSS. That was understandable - I had basically zero skill there - but I wish the interviewer had been more explicit in that I would not be getting a second interview. After getting the first general "work on your tech skills" comment I actually asked explicitly if I could expect to hear about a second interview or not. Probably not the best thing to do, putting the interviewer on the spot like that, but I wanted to be clear on what to expect. The response was more 'beating around the bush' type of stuff - basically the exact same phrasing as before, which I (correctly) took to mean I would not be getting another call. I was disappointed, but I understand why. Overall it was a good experience - the interviewer was courteous and professional, and the conversation started and ended in the expected 30 minute time frame. (By the way, they will call you at the agreed upon time. I was unsure about this leading up to the interview, so I want to make sure to include it here.)
